PLATFORM TRUCK Application filed. April 9,19217; SeraliITo.y 182,374.4

My invention relates to certain improvements in platform trucks of the type in which Vthe front wheels are mounted on an axle swiveled to the body of the truck.

The object of the invention is to simplify the construction of the truck, and to make the parts of pressed sheet metal.`

The invention relates also to certain details described hereinafter.

In the accompanying drawings:

Fig. 1 is a plan View, partly in section, illustrating my improved platform truck;

Fig. 2 is a side View;

Fig. 3 is a longitudinal sectional View on the line 3 3, Fig. l;

Figs. 4 and 5 are detached perspective views of the fifth wheel swivel which is attached to the front axle;

Fig. 6 is a perspective view of one of the bearings for the rear axle;

Fig. 7 is a plan view of a stake-pocket;

Fig. 8 is a sectional view of the stakepoclret on the line 88, Fig. 7 g and Fig. 9 is'a modification of the pivot of the front axle.

The platform 5 is made of sheet metal, and is flanged at the sides and ends as shown in Fig. 3. The flanges are preferably inturned as shown, forming very substantial reinforcing edges for the body of the platform. This construction. is fully set forth and claimed in a companion application filed April 9, `1927, under Serial N0.,182,378.

At the rear of the truck is an axle 6 se cured to bearings 7 by bolts 8 in the present instance. Mounted on the axle 6 are the rear wheels 12 of the truck. n Each bearing is bent from a flat bar.v The portion 9 of each bearing 7 conforms to the shape of the axle, which in the present instance is round. Each of the bolts 8 extends through the portion 9 and through the axle 6 and has a nut thereon which firmly holds the Aaxle in the bearing.

The portions 10 of the bearings are inclined and terminate in pads 11 which are welded or otherwise secured to the body of the platform, and, if desired, the inclined portions 10 may be secured to the flanges of the platform by welding.

The body of fthe :front axle=13isfrectangue lar Iin cross-section; .The ends are.. round to form journals:.for the wheels 14 which may :v

be of ysuitable ity pe. Securedto the vbody of th`eaxle 18 are two plates 15, Fig. l, which are g flanged at theiiw upperV edges as at ,16,

Thertwo plates are secured to theaxleiby rivets 18 andby bolts 19., which alsopass throughybraces 2O located on each side 'of'.,ai

The tongueis locatedon thegpivot pin 25- between -a *lower brace A26 andVI the head -27 of thepin". The/lower brace extends,l at an;

The tubular section is secured by welding at U-c to a plate bent around the tube as shown in Fig. 7, the ends of the plate ez:- tending at right angles to each other and being secured to the corners of the platform by bolts or other fastenings.

In Fig. 9 is shown a modification of the pivot of the front axle, the axle 13a being secured lto a fifth wheel plate 17 by a flanged plate 15a which is bent to receive the axle and to form a flange 16 to which the plate 17 is secured. The plate 28a is shaped similarly to the plate 28, Fig. 3, and is Welded to the platform in the vsame manner. A short pivot pin 25 is used in this instance.

I claim l. The combination in a platform truck; i

Y of a platform; a plate located under the forward end of the platform and secured thereto; a brace secured to the platform and extending under the plate; an axle; two flanged plates secured to the axle; a fifth wheel plate secured to the two axle plates,= said axle plates and the fifth wheel plate being located between' the platform plate and the brace; and a pivot pin carried by the first mentioned plate and brace and extending through the axle and betweenthe axle plates.

2. The combination in a platform truck; 0f a platform having a flange; a plate located under the forward end of the truck and forming a pivot bearing, said platehaving an upright'portion welded to the platform and an inclined rear portion weldedv to the platform; an axle; two plates secured to the f axle and flanged at their upper ends; a fifth wheel plate secured to the flanges of the axle plates; an inclined brace located under the axle and secured to the body ofthe truck; and a pivot pin extending through the brace, axle, fifth wheel plate and bearing plate.

3. The combination in a platform truck,

- of a platform having a flange; a plate located under the forward end of the truck and forming a pivot bearing, said plate having an upright portion welded 'to the platform and an inclined rear portion welded to the platform;

an axle; two plates Secured to the axle andv flanged at their upper ends; a fifth Wheel -plate secured to the flanges of the axle plates; an inclined brace located under the axle and Secured to the body of the truck; a pivot pin Y extending through the brace, axle, fifth wheel plate and bearing plate; a tongue mounted on the pivot pin; braces attached to the axle and tothe tongue; and a handle vsecured to the braces.
